High power narrow bandwidth picosecond PPLN-OPO
A high power, narrow bandwidth, synchronously pumped PPLN optical parametric oscillator is demonstrated. By using a reflective volume bragg grating (RVBG), the signal laser wavelength is locked at 1908.1 nm while the bandwidth is compressed to 0.25 nm with an output power of 4.3 W at the repetition rate of 80 MHz. The beam quality factors in the x and y directions are measured to be 1.30 and 1.68, respectively. The output power stability and directional stability are RMS = 1.4% and 49.58 μrad, respectively. Our results indicate that synchronously pumped OPO is an effective method for generating narrow bandwidth picosecond MIR laser sources.
